Electric Literature of 2698-41-1, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 2698-41-1, name is 2-(2-Chlorobenzylidene)malononitrile, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: A mixture of hydrazine hydrate (1.5 mmol, 80%),ethyl acetoacetate (1 mmol), aromatic aldehydes (1mmol), malononitrile (1 mmol) and starch solution(4 mL), was stirred at desired temperature for 60-90 min. Progress of the reaction was monitored by TLC. After completion of the reaction, the reaction mixture was cooled to RT and diluted with water. The reaction mixture was filtered for the separation of product. The crude product was purified by recrystallization from ethanol to afford pure products in excellent yield.After removal of the extra added (for work-upprocess) water from the filtered solution, the starchsolution (4 mL) is recovered and reused for thesubsequent reaction.
The chemical industry reduces the impact on the environment during synthesis 2-(2-Chlorobenzylidene)malononitrile. I believe this compound will play a more active role in future production and life.
